MOTOR ATTACHMENT FOR CYCLES.

SPECIFICATION forming part of Letters Patent No. 709,550, dated September 23, 1902.

Application filed January 21. 1902. Serial No. 90.653. N0 model.)

To all whom it may concern:

Be itknown thatI, LEONARD MEYRICK MEY- RICK-JONES. engineer, a subject of the King of Great Britain, residing at Bawdeswell, East Dereham, in the county of Norfolk, England, have invented a certain new and useful Improved Means for Enabling Motors to be Used with Bicycles, of which the following is a specification.

Various ways have before been suggested for linking together two bicycles side by side at a distance apart by a connecting-frame. This connecting-frame has also been arranged to carrya motor for driving the driving-wheels of the bicycles.

In place of giving motion from the motor to the driving-wheels of the bicycles I provide the connecting-frame, preferably at its rear end, with a driving road-wheel and give motion to this road-wheel from the motor, leaving the bicycle driving-wheels to be driven by ordinary pedal-gear whenever desired. To insure that the driving-wheel carried by the connecting-frame shall always bear upon the ground with sufficient pressure, I also in .some cases provide springs, which tend to depress this wheel below the level of the bicycle driving-wheels. Similarly a frame provided with a driving road-wheel actuated by a motor may be coupled to one side of a bicycle at a distance from it and the drivingwheel kept pressed down by a spring.

My improvements are shown in the drawings annexed.

Figure 1 is a side view, Fig. 2 a back view, and Fig. 3 a plan, of two bicycles coupled by a connecting-frame provided with a roadwheel and motor for driving this wheel. Figs. 4, 5, and 6 show similar views of a modification, in which parts of the back bar of the connecting-frame form springs to keep the driven road-Wheel pressed down onto the ground. Figs. 7 and 8 show a back view and plan of another modification, in which the construction of the connecting-frame is modified. Figs. 9 and 10 show a back view and plan of a similar frame carrying a road-wheel and motor for driving it coupled to one side of a cycle. Fig. 11 shows one way in which the stays and cross-bars of the frame may be made adjustable in length.

In Figs. 1, 2, and 3, a a are two bicycles. l) l) are clamps clamped to the heads and backstays of the bicycle-frames. o c are other clamps coupled by swivel connections 0 to the clamps b, as described in another application for patent made by me, Serial No. 75,777. The clamps c grasp two longitudinal rods forming part of a frame d, which thus serve to connect together the two bicycles side by side at a distance apart. 6 is a motor, the frame of which is secured to the back bar C1 of the frame d and bya cross stay-barf to the front end of one of the longitudinal side rods of this frame. g is a road-wheel revolving around part of the back bar (1' of the frame (1, which thus serves as its axle. h is a toothed wheel fast with the wheel g, and 11 is a pinion gearing therewith and fast upon the axis of the motor 6.

In Figs. 4, 5, and 6 a portion of the back connecting-bar d near each end is made to form a spring 01 and serves to press the driving-wheel g downward against the ground, the springs giving way in a vertical direction, but remaining stiff horizontally. The clamps c are also done away with, and the clamps I? attach the ends of the front bar (I and back bar d directly to the heads and backstays of the two bicycles. Stay-bars k are also made to extend directly from the back bar to clamps Z,secured to the front bar. The front bars d may be connected by joints d to the clamps I). They may also be made extensible in length, preferably in the manner illustrated in Fig. 11. In Figs. 7 and 8 a similar construction is shown, except that in place of the stay-bars is diagonal tie-bars m are made to extend from the motor-frame to the clamps Z7, em bracing the bicycle steering-heads. The front bar d is also shown to be secured by clamps m to the front portions of the diagonal tie-bars m. The tie-bars m may be made adjustable in length and be jointed by joints m to the clamps b. In Figs. 9 and 10 a similar construction is shown for connecting a road-wheel and a motor by which it is driven to the frame of a single bicycle. The back bar 01, which at its outer end serves as an axle for the road-wheel g, is at its other end secured to one of the backstays of the bicycleframe, and a diagonal tie-bar 'm extends from the motor-frame to the clamp b, which em braces the bicycle steering-head.

The back bar or axle d may be made adjustable in length in the manner illustrated in Fig. 11, so that the clamp 17 at the extremity of the stay or tie bar may be brought into position to clamp the steering-head at Whatever distance the steering-head may be from the point at which the axle d is secured to the frame.

Preferably in all cases the road-wheel g is provided with an inflated pneumatic tire.

In all the figures similar parts are marked with the same letters of reference.

What I claim is 1. The combination of two bicycles,a framework connected to the frame of both bicycles by clamps and coupling them side by side at a distance apart, a road-wheel carried by the framework and a motor driving this wheel also carried by the framework.

2. The combination of two bicycles,a framework connected to the frame of both bicycles by clamps and coupling them side by side at a distance apart a road-wheel carried by the framework, springs acting to press downward this road-wheel and a motor driving the roadwheel.

3. The combination of two bicycles side by side at a distance apart, a tie-rod, clamps at its ends secured to the two bicycle-frames, a road-wheel mounted upon and capable of being revolved around the rod, a motor attached to the rod and driving the wheel, stays extending from the rod to the ends of the bicycle-frames and a tie-bar holding apart the ends of these frames.

4. The combination of two bicycles side by side at a distance apart, a tie-rod, clamps at its ends secured to two bicycle-frames, a roadwheel mounted upon and capable of being revolved around the rod, a motor attached to the rod and driving the wheel, portions of the rods formed as springs to force the roadwheel against the ground, a tie-bar holding apart the ends of the bicycle frames and cross-stays for keeping the rod and tie-bar at right angles to the bicycle-frames.

5. In a motor attachment for bicycles the combination of a rod, a road-wheel mounted upon and capable of being revolved around the rod, a motor attached to the rod and driving the wheel, a clamp at one end of the rod by which it can be attached to the bicyclef-rame so as to stand out sidewise at right angles to it, and a stay fast at one end with the rod and at the other adapted to be secured to the bicycle-frame.

6. In a motor attachment for bicycles the combination of a rod, a road-wheel mounted upon and capable of being revolved around the rod, a motor attached to the rod and driving, the wheel, a clamp at one end of the rod by which it can be attached to the bicycleframe so as to stand out sidewise at right angles to it, a portion of the rod formed as a spring to force the road-wheel against the ground, and a stay fast at one end with the rod and at the other adapted to be secured to the bicycle-frame.
